"With markets about to close for the next 2 days, the question on every trader's mind is: "should i carry risk over the weekend, or should I dump it all in case North Korea fires another test, or non-test, ICBM launch"

"And while the report has yet to be confirmed by other news outlets, traders are furiously hitting refresh on the website of 38North.org for the daily satellite image update of North Korea's missile launch preparedness, which has yet to hit and which could mean the difference between another sleepy, boring open on Monday and a VIX surging above 20, 30 or more depending on what 'path' Kim Jong-Un picks over the next 48 hours."

VIX = VOLATILITY INDEX. "The CBOE's Volatility Index, known by its ticker symbol VIX, is a popular measure of the implied volatility of S and P 500 index options, calculated and published by the Chicago Board Options Exchange (CBOE). It is colloquially referred to as the fear index or the fear gauge."
